P10221: Baja 1 (Baja Driveline Test Development)/public/
Table of Contents
- A chain guard enclosure will be secured to the dyno
table every time the Baja engine is run on the dyno. A
complete installation procedure will be included in the
operating procedure/safety document.
- Complies with OSHA standards.
- To prevent damage to the dyno or engine if something goes wrong, we are using a drive system that incorporates a safety hub with shear bolts. When a toque is encountered that is over a specified amount, the bolts will shear and the sprocket on the Briggs output shaft will spin in place.
- There will also be manual shut off switches in both the dyne controller room, and on the Briggs engine.
- The current exhaust system in the dyno room is inadequate. A new system will be installed by December.
- Gasoline fumes could accumulate under the dyno table after continuous use, or if there is a gas leak. To prevent these fumes from becoming concentrated, a fan will be placed in the room to circulate the air.
- The engine stand has a handle to move the engine between the various tilt positions.
- Hot surfaces will be identified clearly in the operating procedure/safety document.
- A complete step by step how-to procedure will be provided to the Baja team in MSD 2. This document will also include safety considerations throughout its entirety. Some considerations that this document will address are:
Setting up the engine on the dyno:
- The power needs to be off before setting up the engine on the dyno.
- The engine stand, chain guard, and drive components can be transported by a movable cart to the dyno room to prevent the engine from being dropped.
- All wires need to be bundled and clear of any moving parts or hot surfaces.
- Gasoline is stored in a secure room if refueling is necessary. The operating procedure will specify how much there can be in the dyno room at any given time.
- The room exhaust system must be placed a certain distance from the engine muffler to draw the correct amount.
- The chain guard will be placed over the entire drive system and secured with 4-6 bolts.
Running the Dyno:
- The dyno room door needs to be closed when the dyno is running.
- The exhaust fan needs to be running and in the correct position in relation to the muffler outlet of the engine.
- The chain must be tight by having the tensioner engaged to a pre-determined position.
- The oil level in the engine must be checked before turning over the dyno to prevent the engine from seizing.
- The throttle connection needs to be checked and verified that everything is tightened.
- The shear bolts need to be used and the proper torque applied whenever the Baja engine is tested.
